APPARATUS FOR MAKING HOLES IN MATERIAL TO RECEIVE PRESERVATIVE FLUID.

Specification of Letters Patent.

Patented Mar. 8,1921.

Application filed June 13, 1914. Serial No. 844,923.

To all whom it may concern:

Be it known that I, MAX Rtirme, a subject of the Emperor of Germany, residing at Berlin, Empire of Germany, have invented certain new and useful Improvements in Apparatus for Making Holes in Materials to Receive Preservative Fluid, of which the following is a specification.

This invention relates to improvements in apparatus for making holes in materials to receive a preservative fluid, and has for its object to provide an improved apparatus of that character which will be efiicient and practical in operation.

My invention comprises the construction of an apparatus which is suitable for perforating, pricking, or making indentations in materials, such as wooden ties, telephone poles, or the like, which are to be impregnated with creosote, or other preservative fluid. It is well known that the application of such preservative fluids is attended with much difiiculty and expense where it is desired to thoroughly impregnate the ties, or blocks, or the like, and to aid in this impregnation I provide a device carrying a plurality of needle members, together with means to force them non-rotatably into the material to be treated. By using comparatively slender needles, or the like, the fiber of the wood, or other material, is uninjured. and while the impregnation is meterially assisted, the strength of the material is not appreciably lessened. I also provide means to guide and strengthen these needle members while they are being driven into the material to be treated so as to eliminate as far as possible breaking and bending of such needle members, and this means when used with the device shown and described will serve to straighten the needles, or the like, as they are withdrawn from the material, should they accidentally become bent by striking a knot or the like in the body of the material.

My invention also comprisesmeans for forcing the needle members into the material, this means being also utilized to positively withdraw the needle members after such perforation or pricking. These and other objects will be set rorth and described in the following specification and accompanying drawings, in which- Figure 1 is a transverse section through a portion of an embodiment of my device showing its operation on a Wooden tie, for example.

Fig. 2 is a sectional view at right angles to the view of Fig. 1, showing certain parts in elevation.

Fig. 3 is a perspective view of the guiding member;

Fig. l is a detail plan of a portion of the guiding member, showing a needle in position therein;

Fig. 5 is a detail View, showing the swivel connection of the operating rod with its socket.

Fig. 6 is a transverse section through a portion of another embodiment of my deviccg, showing its operation on a wooden tie; an

Fig. 7 is a sectional view at right angles to the view of Fig. 6, showing certain parts in elevation.

Like numerals refer to like elements throughout the drawings, in which 10 designates generally a block of wood or a tie, or the like, which is to be operated upon by my device previous to its impregnation. This tie or block 10. is located upon a.- supporting plate 11, from which extend upwardly posts B, B Across the tops of these posts, and supported thereby, is located the cross bar C, the same being limited against upward movement by the nuts I), Zi threaded on posts B B This cross bar is enlarged at c, this enlarged portion being centrally apertured and threaded.

A screw-threaded operating rod D engages the threaded aperture in the enlarged portion 0, and extends therethrough and c0- acts therewith. The rod D maybe rotated by a suitable handle orarm, not shown. At its lower extremity this rod seats in and coacts with a socket d, a swivel connection being provided between the rod and the socket, as shown in Fig. 5. This socket is carried by a press plate E, the aforesaid swivel connection enabling this plate to aline itself within the necessary limits to compensate for inclinations or irregularities in the surface of the material being treated, and also permitting rotation of the rod D relative to the plate E.

At its sides the plate E is provided with the downwardly extending plates E, E. Between these plates, on its under surface, the plate E is provided with the undercut grooves or notches e, in which are seated and firmly held the enlarged heads e of the plates E these plates being parallel to and similar to the plates E, E All of these downwardly extending plates are provided with undercut, or dove-tailed, notches or grooves 6 in which are fitted heads 9 of needles G, these heads being flattened in one direction and drawn out in right-angular direction to closely fit the notches 6*, as clearly shown in Fig. 2.

A guide member F is located on the material or block 10, where it is desired'to prick or perforate the same, as shown in Fig. 1, for example. This guide member or block is provided with slots F extending therethrough, these slots being spaced apart for alinement with the depending plates E, E E as clearly shown in Fig.1, and the said slots are of a width approximately equal to the thickness of the said plates to insure a close fit of the plates therein while permitting reciprocation of the said plates in the said slots. The heads 9 of the needles G, as stated above, are flattened to a thickness approximately equal to the thickness of the plates E, E and E this thickness being less than the diameter of the body of needles G, as shown in Fig. 4. One side wall of each of the slots F is provided with dished-out portions or grooves f in alinementwith the needles, these grooves being arranged and designed to permit passage through the said slotsof the needles 7, as shown in Fig. 4, at the same time prevent ing bendingxof the said needles in the slots, as will be apparent, and assisting. in the allnement of the entire device.

In Figs. 6 and 7 I have illustrated another embodiment of my invention, which I have found to be preferable to the form shown in Figs. 1 to 5. In this modified form of my invention I make use of fiat needles substantially rectangular in cross section and of relatively great width as compared with the thickness thereof- These needles arearranged with their longer horizontal axes parallel to the wood fibers of ithetie which is to be perforated, and are provided with knife-edge ends which are adapted to enterthe wood parallel to the fibers thereof. These'blades produce openings in the wood, which not only ofier a .large area for the preservative fluid to enter the wood, but also in ure the cohesiveness.

of the wood fibers to a much less extent than a. round needle of the same, or even a less, cross-sectional area. i

,Beferringto Figs. 6 and 7. the supporting plate is designated by thefnumeral 11',

and the posts B and Bextend upwardly therefrom to term supports for the cross bar 0 which 1s secured in position thereon by the nuts Hand 7)". The cross bar is provided with the enlarged central portion ct having a threaded aperture therethrough adapted to be engaged by a threaded operating rod D, which forms a swivel connection at its lower end with the socket d.

The socket d is carried by a press plate H, which is provided with. depending side flanges h and end flanges 7a. A series of needle-carrying plates K are adapted to closely fit within the flanges of said press plate, where they are secured in position by the bolts L and nuts L. Each of the needlecarryingplates K is provided with a plurality of notches 7c in the side thereof, each notch being provided with inwardly extending lugs which form shoulders I0 An undercut notch is thus formed which is adapted to engage a similarly formed head of a needle member M. The needle members have the same thickness as the depth of the slot and may be conveniently cut from steel plate to have the form of head shown in Fi 7. This form of needle thus presents an advantage over the first form described. in that it may be more conveniently formed for making a tight and rigid connection with the needle-carrying plate. Each of these needle members has a relatively large width and small thickness. as above stated, and preferably has its edges beveled, as shown at m. The lower end of each needle is provided with a knifeedge, as shown at M. which is arranged to enter the tie 10' parallel to the fibers o'f saidtie. plurality of needles are carried by each plate, each in alinement with the other. but the needles carried by the several plates may be arranged. in staggered relation, as shown clearly in Fig. 7.

A guide member N is arranged beneath the press plate. and isprovided with a series of lonuitudinal slots P. which extend verticallv therethrough and form guides for' provided with slots 'whichaline with those in the guide member, and theslots in each of said members are made to closely fit the lateral vsurfaces of the needles to prevent bending thereof as they are entering the tie. It will be obvious that in the use of this form: ofmy invention it is notnecessary to provide grooves in therguide member at the sides of. the slots, for the reasonthat the needles being of bladeform will haveatendency. to bend only in one plane. 1 .11 have found-that. where economy is ad- :visable, it is sufficient to. thoroughly impregnate the ties, blocks, or the like, only at the points where there, is greatest danger of rotting:- and decay, such, for example, as the seat of the tie plates in the case of a railway tie, or the portion of a telephone pole adjacent to and just below the surface of the ground in which it is embedded. Consequently, I have shown my device as constructed for and operating only upon a portion of the block 10. It will be understood that the dimensions can readily be altered to suit the nature of the work being done, and that the form of my device may be changed to conform to materials of circular or other contour.

It will also be obvious that my invention is susceptible of many modifications and changes, and I do not Wish to be restricted to the showing in the accompanying drawings, or the above description, beyond the scope of'the appended claims.

I claim 1. In a device for making indentations in materials to receive preservative fluid, a press plate, a needle carrying plate carried thereby, a plurality of knife-edge ended needles carried by said plate, said needles being relatively close together with their knife-edge ends lying in parallel planes, and means to operate said press plate to force said needles into a wooden block or the like with said knife-edge ends substantially parallel to the grain of the wood.

2. In a device for making indentations in materials to receive preservative fluid, a press plate, a needle carrying plate carried thereby, a plurality of knife-edge ended needles carried by said plate, said needles being located relatively close together with their knifeedge ends lying in parallel planes, means to operate said press plate to force said needles into a Wooden block or the like, and means to guide said needles, said guiding means comprising a member having parallel slots therein adapted to engage and contact closely with the opposite sides of said needles to prevent bending thereof.

In an apparatus for making holes in materials to receive preservative fluid, a frame, a vertically movable press plate carried by said frame, means for reciprocating said press plate, said press plate having a chamber formed in its under side, a plurality of parallel needle-holding plates mounted in said chamber, a plurality of flat needle members carried by the holding plates and depending therefrom in rows, said needle members having sharpened lower extremities forming knife edges, and a loosely mounted guide member adapted to rest upon the member being operated upon and having longitudinally extending parallel slots therethrough each adapted to receive and guide a row of needles.

In testimony whereof, I have subscribed my name. H
